My new Grillo Climber 9.16 has really impressed me. It powers up and around my steep slopes without an issue and turns safely. Although I only have 3 acres of land I justified this investment with two important points . User safety and bushfire prevention. I rolled my Greenfield mower a few years ago and it scared the hell out of me, and for a few years I didn't slash my grass at all. This lead to an increased fire risk over summer. With my Grillo Climber I slash away every few weeks during winter and the whole hill looks like a bowling green. Now I don't have to worry so much about bush fires, and during winter I can safely and confidently slash my hillside. It’s a good quality product and obviously built to last.
